Application fled July 21, 1926. Serial No. 123,889.

Our invention is an automobile parking device intended to raise the vehicle wheels a curb or other more or less. inaccessible place.

An object of our inventlon 1s a parking device carried by an automobile and operated thereby, so that the regular running wheels can be elevated and small transverse.

conveying wheels may be substituted. These wheels are elevated and depressed by a ]ack type of device elevating both the front and the back' wheels. One or more of these wheels may be driven so as to bodily move the automobile in a sidewise direction, thereby allowing parking same close to a curb and parking a number of vehicles simllarly equipped, close together.

A more particular object of our invent on is providing pairs of pivotally mounted smalls wheels connected to the front and back axles of an automobile and operating these wheels by a screw-jack type of device to elevate same and depress same into engagement with the ground, thereby elevating the ordinary running wheels of the vehicle.

Another object of our invention is to interconnect a pair of these wheels on the front and back axle to positively rotate same, thereb moving the vehicle sidewise the desired istance.

Our invention will be more readily understood from the following description and drawings, in which;

Figure 1 is a plan view of our parking device, illustrating only sufficient details of the automobile to show the attachment thereof;

Fig. 2 is a vertical longitudinal section on the line 22 of Fig. 1, in the direction of the arrows;

Fig. 3 is a rear elevation in the direction of the arrow 3 of Fig. 1, with parts broken away;

Fig. 4 is a transverse section on the llne 4-4-. of Fig. 1, in the direction of the arrows;

Fi 5 is a detail section on the line 55 of Fig. 1, in the direction of the arrows, showing the driving train for operating the smallwheels.

The jacking mechanism of our parking device is constructed substantially as follows,

having reference particularly to Figs. 1 to 4.

The front axle of an automobile is .designated by the numeral 1', the rear axle housing by the numeral 2 and the ordinary runnmg wheels by the numeral 3. A strong supporting bracket 4 is clamped to the front axle and extends rearwardly and a bracket 5- is attached to the rear axle housing, ex-

tending both forwardly and rearwardly therefrom. 1

In the'front axle housing shown particularly in Fig. 4, longitudinal pivots 6 form a connection for the wheel legs 7 and the brackets, these wheel legs having yokes 8 at the base in which are mounted small wheels 9. Jack rods 10 are connectedthrough suitable yokes 11 with the wheels. lead upwardly and cross each other and are threaded through nuts 12. The rear axle mounting is substantially the same, being These rods shown in Fig. 3, there being pivots 13 for i the legs 14 and to which the wheels 15 are connected.

The rear jack rods 16 are connected through yokes 17 to the wheels and threaded through the rear nuts 18'. The nuts 12 are supported in a sleeve 19 which is attached rigidly to a curved frame arm 20 and the rear nuts 18 are supported in a similar sleeve 21 rigidly connected to the bent arms 22. These arms are rigidly connected to the front and rear brackets 4 and 5' respectively.

Each of the nuts 12 and 18 is provided with a bevel gear 23 which mesh with bevel gears 24 on longitudinal shafts 25 and 26 extending lengthwise of the vehicleon opposite sides thereof.

The driving arrangement for the jacks is substantially as follows, having reference particularly to Figs. 1, 2 and 3:

A transverse shaft 27 journaled in supports 28 and 29 has a pair of helical gears 30 which mesh with helical gears 31 on the longitudinal shafts 25 and 26. This shaft 27 is continued at one end and has a worm gear 32 meshing with a worm 33, the latter being mounted on the motor shaft 34. or a continuation of said shaft; the motor 35 being supported on part of the bracket .5 of the rear axle housing. Such worm shaft has a part of the engine or body frame or 'of the rear axle housing. -When the motor is operated in the proper direction by the medium of theh worm 33 and the worm gear 32, the transverse shaft 27 is rotated, thence the I. I longitudinal shafts 25 and 26 are rotated through the medium of the helical gears 3O and 31. The bevel. gears 24 on each end ofboth of the shafts 25 and 26 then operate the bevel gears 23 formed integral w1th the nuts 12 and 18, thereby actuating the ]8.Ck rods 10 and 16 depressing the small wheels 9 and 15 for the front and rear axle respectively. This action lifts the driving wheels of the vehicle above the ground as illustrated in Figs. 3 and 4. Y The mechanism for providing lateral motion is substantially as follows, having reference articularly to Figs. 1, 2 and 5;

As s own in Fig. 2, the yokes 11 and 17 are provided with a socket in which is secured a frame 41 which may be tubular or formed of suitable rigid bars, this frame being clam ed by set screws 42 or the like. A long shaft 43 forming the, driving axle for one pair, of the small wheels 9 an 15 is centered within this frame. A box 44 contains a train of gears; this co prising driven gear 45 on the Shaft 43, "a."

idler pinion 46 on an idler shaft 47, a large gear 48 on the same shaft, this latter meshing with a pinion 49 on the motor shaft 50 of the motor 51;' this latter being suitably clamped or attached to the frame 41. It will be understood that there is suitable electric wirin from the. motor to a control device ad acent the operators compartment of the automobile.

When it is desired to move the vehicle transversely after being elevated as above;-

described, it is merely necessary to actuate the motdr to drive same in the proper direction, whence by the gear reduction syste above mentioned the electric motor 51, through the medium of its shaft 50 operates the gears in the gear box 44 and thereby rotates the shaft 43 which latter being keyed or otherwise secured to the small wheels 9 and 15 rotates same and formsg' the, driving medium to contact with the igrou'nd for transporting the vehicle sidewise to the desired parking position. i

It will be understood that this transverse motion may be stopped at any time by. st0p-.

ping the motor an on account of the gear reduction system a sufiicient brake is thus Egovided so that this sideways motion may stopped at any desired position. When down hil the vehicle is suitably parked is may be left elevated as above described or lowered 'on to its drivingwheels if desired.

and to move the automobile bodily. sideways.

It will be manifest that our desi -in its general construction and in speci 0 details may be considerably. modified to adapt same to different types of automobiles and if desired the various parts may be incor orated in the automobile structure. Such c anges, however, would be within the spirit of our invention as set forth in the description, drawings and claims.

As above mentioned our arking device allows sidewise movement 0 an automobile in either direction, this being necessar to park against a curb and to move the ve icle away from the curb, and also forms a useful feature in a garage for placing a car where desired. It is also obvious that our jacking arrangement independent of the lateral movement, is of manifest utility in jacking a car for repair work or the like and that also on hi s an automobile ma be jacked up elf its driving wheels on to the transverse wheels, thereby preventing the car from rolling Having described our invention, what we flaim is:
